Struct UpdateTableRequest 

pub struct UpdateTableRequest {
    pub id: Option<Vec<String>>,
    pub predicate: Option<String>,
    pub updates: Vec<Vec<String>>,
}

UpdateTableRequest : Each update consists of a column name and an SQL expression that will be evaluated against the current row’s value. Optionally, a predicate can be provided to filter which rows to update.

Fields

id: Option<Vec<String>>

predicate: Option<String>

Optional SQL predicate to filter rows for update

updates: Vec<Vec<String>>

List of column updates as [column_name, expression] pairs

Implementations

impl UpdateTableRequest

pub fn new(updates: Vec<Vec<String>>) -> UpdateTableRequest

Each update consists of a column name and an SQL expression that will be evaluated against the current row’s value. Optionally, a predicate can be provided to filter which rows to update.

Trait Implementations

impl Clone for UpdateTableRequest

fn clone(&self) -> UpdateTableRequest

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for UpdateTableRequest

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for UpdateTableRequest

fn default() -> UpdateTableRequest

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for UpdateTableRequest

fn deserialize<__D>( __deserializer: __D, ) -> Result<UpdateTableRequest, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for UpdateTableRequest

fn eq(&self, other: &UpdateTableRequest) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
